2007—2009年,临澧县连续3a实施一季超级杂交晚稻“种三产四”丰产工程示范,经专家测产验收,3a平均单产达9.44t/hm2,核心示范片平均单产达到11.4t/hm2。通过总结、分析项目实施的技术措施和保障措施,提出了适时播种、场地育苗、乳苗浅栽、合理稀植、配方施肥、科学管水等配套高产栽培技术。
In 2007-2009, Linyi County carried out one-season super hybrid late rice “demonstration of three kinds of high yielding four” high yield demonstration projects. The average output of the three years was 9.44t / hm2 and the average yield of the core model reached 11.4t / hm2. Through summarizing and analyzing the technical measures and safeguard measures of the project implementation, the paper puts forward the high-yielding cultivation techniques such as timely sowing, field nursery, shallow nursery stocking, rational sparse planting, formula fertilization, scientific management of water and so on.
